QuestionMake a DataGridView column editable Pin

I've been at this on/off for about a week now. I put it to the side & move onto other things and now I'm back to it.
I have a datagridview (dgvScheduleInfo). In its properties I have the "ReadOnly" set to true. I have 6 columns (0-5). The last column ("Notes") I want to make editable if someone clicks on a "Edit Notes" button. Sounds simple enough.

I've used the following code to no avail:
dgvScheduleInfo.Columns(5).ReadOnly = False

I've tried:
dgvScheduleInfo.Columns("Notes").ReadOnly = False

The code above errors out with a "Object reference not set to an instance of an object." even though when I step through the code it shows "Notes" as the name.

I've tried hard-coding a value for testing purposes:
dgvScheduleInfo.Rows(3).Cells(5).ReadOnly = False

and that hasn't worked.

And this is ultimately what I want to work:
dgvScheduleInfo.Rows(dgvScheduleInfo.CurrentRow.Index).Cells(5).ReadOnly = False

When I step through the code, I only get an error on the one I specified. Other then that though the code steps through fine but does not set the column I'm requesting to be editable.

Now yet another curveball...
If I use:
dgvScheduleInfo.ReadOnly = False

It works fine but turns ALL the cells on which I don't want. I only want the "Notes" (or column 5) to be editable.

I've changed the "EditMode" to a couple of different things as well. Nothing.

Hopefully it's something very easy I'm missing.

I haven't changed any of the properties on the datagridview control when I dropped it on my form either. Also I'm using a tableadapter and dataset to populate my datagridview.

The only code in my command button is what I've stated above.

Thanks for any help on this.
